CompTIA Security+ (SY0-601) — Question 25

Which of the following would detect intrusions at the perimeter of an airport?

Answer options

• A. Signage
• B. Fencing
• C. Motion sensors
• D. Lighting
• E. Bollards

Correct answer: C

Explanation

Motion sensors are specifically designed to detect movement and can alert security personnel to potential intrusions at the airport's perimeter. While signage, fencing, lighting, and bollards can contribute to security, they do not actively detect unauthorized access like motion sensors do.
